Hi Bob. Another few things in this... Last I looked (2 years ago) they only make these pans for a 2 piece rear main block. If you have a newer 1 piece rear main you might have trouble finding one. If someone here on the forum knows of a 1 piece rear main pan they could chime in. The mod is pretty easy though. I did the pan mod outlined on the v8monza site with a 1 piece rear main pan. You can buy a little more clearance by changing out those 2 grease fittings to set screws and just pop grease fittings in to re-shoot.
If you have clearance on the top side you could raise the motor a bit with new/modified plates. Just keep the drive line angle in check if you do.
